Answer:

Hi!

The answer to:

a. 6 bits.

b. 9 bits.

c. 26 bits.

Explanation:

a. For the states of the U.S.A, you need 50 or more combinations to represents each element.

If you use 6 bits, the possible combinations are 2⁶ = 64.

b. For days in a year, you need 365 or more combinations to represents each element.

If you use 9 bits, the possible combinations are 2⁹ = 512.

c. For inhabitants of California, you need 36,457,549 or more combinations to represents each element.

If you use 26 bits, the possible combinations are 2²⁶ = 67,108,864. If you use 25 bits instead of 26, then you have 2²⁵ = 33,554,432 combinations. These possible combinations are not enough to represent each inhabitant.

BigorU [14]

Answer:

import java.util.Scanner;

public class ContactInformation

{

public static String GetPhoneNumber(String[] nameVec, String[] phoneNumberVec, String contactName, int arraySize)

{

for(int i=0;i<arraySize;i++)

{

if(nameVec[i].equals(contactName))

return phoneNumberVec[i];

}

return "Contact doesn't exists!";

}

public static void main(String[] args)

{

int records;

Scanner sc = new Scanner(System.in);

System.out.print("Enter the size of contact List :");

records=sc.nextInt();

String[] contactNameList=new String[records];

String[] phoneNumberList=new String[records];

String contactName;

System.out.println("Enter the contact name and phone number :");

for(int i=0;i<contactNameList.length;i++)

{

contactNameList[i]=sc.next();

phoneNumberList[i]=sc.next();

}

System.out.println("Enter the name of the contact to be searched :");

contactName=sc.next();

System.out.println(GetPhoneNumber(contactNameList,phoneNumberList,contactName,records));

}

Explanation:

In the following the function defined above for getting the contact

number on the basis of contact number provided we are checking the contact name list if we are able to find the contact name and if we did we return the contact number on the same index from the contact number list

which we found in the contact name list.

Call your function from Example 1 three times with different kinds of arguments: a value, a variable, and an expression. Identif

Blizzard [7]

Answer:

Example 1:

def function(num):

print(num*2)

Example 2:

function(5)

num = 2

function(num)

function(3-1)

Explanation:

Given:

See attachment for complete question

To start with Example (1)

def function(num):

print(num*2)

Note that; the above code segment which doubles the parameter, num could have been any other code

In Example (1), the parameter is num

For example (2):

We can call the function using:

#1. A value:

function(5)

In #1, the argument is 5; a value

#2. A Variable

num = 2

function(num)

In #2, the argument is num; a variable

#3. An Expression

function(3-1)

In #3, the argument is 3-1; an expression
